2023 Map of Lost Valley

About this map

The Owyhee River Wilderness and its protected waterways dominate the southwestern corner of this Idaho landscape. High desert hydrology is the primary story of this region, defined by the winding course of the Battle Creek Wild and Scenic River and its tributary, Blue Creek. The terrain is characterized by broad basins and depressions like Bull Basin and Lost Valley, punctuated by isolated features such as Dollar Butte. Human infrastructure is largely confined to water management and travel corridors, seen in the series of man-made structures including Dry Cr Reservoir Number Seven and Dry Cr Reservoir Number Four. These reservoirs, along with various localized water sources like Wildhorse Spring and Lost Valley Springs, reflect the critical importance of water rights and grazing resources in this remote section of Owyhee County. Connecting these disparate points is the primary thoroughfare of Battle Creek Rd.
